evolve: adapt for changed @command decorator

Core changed the hacky "^command" syntax to be a proper decorator
option in fa88170c10bb (help: adding a proper declaration for
shortlist/basic commands (API), 2018-10-12). This patch makes evolve
compatible with that.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once

  $ hg init test1
  $ cd test1
  $ echo a > a
  $ hg ci -Aqm "added a"
  $ echo b > b
  $ hg ci -Aqm "added b"
